About

Who publishes this.

NozzleCheck is an independent knowledge base for print-on-demand production: apparel, drinkware, wall art, objects, embroidery, books, and the industrial digital printing behind all of it. It is not owned by a vendor, a platform or a trade body, and it carries no vendor money.

Who writes it

One editor decides what runs. Research and drafting are AI-assisted; every claim is verified against a primary source, and a person approves everything before it goes out. We do not badge individual pages as AI-generated, because the relevant fact is not which tool typed the words. It is whether the claim is sourced, and who stands behind it.

Corrections and questions go to hello@nozzlecheck.com, and they are read by the person who decides what runs.

The four rules

What is already checked

Issue 001 runs to 8 sections and 247 sourced references. Every claim we have rated sits in the verdict register — 72 so far, of which 18 did not survive the check. Failed checks are published. We do not quietly drop the claims that did not hold, and a verdict that later turns out to be wrong is corrected in the open, with the original reasoning left on the page.

How a claim becomes a verdict

The source is fetched and read. A verdict has to quote the exact span it rests on, and that quote is checked against the fetched page by a script. A verdict whose evidence cannot be found in the source is discarded before anyone sees it. If a publisher blocks automated access, we say so and publish no verdict; we do not disguise the fetcher as a browser to get around a refusal. The full method, including the five ratings and what each one means, is on the methodology page.

The letter

Pulse goes out on Mondays: one lead item worth taking into a shift plan, a handful of signals with the reasoning attached, and the compliance dates close enough to matter. Every item carries its source. A claim without a working link does not go out.

The same work reaches two other places. The atlas holds the figures a shop is exposed to — input costs, customs thresholds, market estimates — each with the source that states it and the day we last read it there. The podcast is newer and thinner: one episode so far, read from the same checked material rather than written separately.
